It sure looks like Thursday night will be the coldest night of the season so far in the News 9 area as the low temperatures generally drop down to the -15 to -20 degree range. As usual there probably will be some colder pockets, maybe even reaching into the -20s. Thankfully the northwest to west winds will be lighter, around 5 mph. As such the wind chills won't be super low, but could still touch -25 or -30 briefly in a few cases. A WIND CHILL ADVISORY has been posted for much of the News 9 viewing area for Thursday night into Friday morning. Please bundle up and protect from frostbite if you must venture out. Skies will be clear and then stay mostly sunny for Friday thanks to the arctic high pressure overhead.
As the high pressure departs to the southeast, we will see southerly winds increase later in the day. In fact the south winds could be around 20 mph Friday night and become southwest Saturday. While the wind will feel cold, it will help to pull warmer air back into Wisconsin. Lows Friday night should be in the 0s then rise to the 10s overnight. Highs should reach close to 30 degrees Saturday. We have a good chance of some scattered light snow showers Saturday, with most of the threat ending by early to mid-afternoon. Accumulations should be very minor, maybe one-half inch or so.
Somewhat cooler air will work back in for Sunday on northwest winds. Lows should be around 8 with highs in the 10s north to low 20s south even with some sunshine. That is below normal of course.
A new storm system will come into the middle of the country late Sunday night and Monday. It will likely bring us several waves of snow. At this time the data suggest we could see at least several inches of snow through late Monday night although the placement of the heaviest swath is still rather uncertain. The system will also pull in milder air with highs near 30 Monday. A few flurries may linger into early Tuesday otherwise Tuesday should be mostly cloudy and breezy. Highs may stay in the lower to mid 20s.
Even colder air is projected to slide in Wednesday with highs in the 10s. At least there should be a lot of sunshine. Dry conditions may hang around into next Thursday with a slight rebound in temperatures as highs climb to the mid 20s.
